Aerospace part performance is influenced by geometric tolerances, microstructure, residual stress, and surface finish, among other factors. These characteristics are developed through the entire processing sequence, from primary processing, through forming and machining. Computer simulation has proven to be a valuable tool for understanding the role of manufacturing processes on part quality. This presentation will examine how recent advances in finite element modeling technology have enhanced machining process simulation. Simulation technology has enabled the coupling of machining process models with residual stress prediction, microstructure models, and the influence of forming and heat treatment processes.
Simulation results include bulk and surface residual stress, bulk and surface microstructure, and bulk distortion. An understanding of these values support the selection of manufacturing process parameters to improve part quality while reducing production cost.
